Smog Advisory Lifted

TORONTO, Aug. 3 /CNW/ - Effective immediately, the Ministry of the
Environment has lifted its Smog Advisory for the following regions:
------------------------------------------------------------------------
Belleville-Quinte-Northumberland Niagara
------------------------------------------------------------------------
City of Hamilton Oxford-Brant
------------------------------------------------------------------------
Dunnville-Caledonia-Haldimand Sarnia-Lambton
------------------------------------------------------------------------
Elgin Simcoe-Delhi-Norfolk
------------------------------------------------------------------------
Kingston-Prince Edward Windsor-Essex-Chatham-Kent
------------------------------------------------------------------------
London-Middlesex
------------------------------------------------------------------------
A cold front has moved south of the province, resulting in northwesterly
winds and cleaner air across the forecast regions listed above.
Smog is a hazy mix of pollutants made up of ground-level ozone, fine
particulate matter and other pollutants. During the summer months, more than
half of Ontario's smog-causing pollution originates in the United States. In
cooler months, domestic sources can be significant contributors to the
formation of fine particulate matter.
The website www.airqualityontario.com contains a list of "spare the air"
actions (www.airqualityontario.com/science/spareair.cfm) to help combat smog
and minimize its effect on sensitive populations. If you want to learn more
